基于GeoAgent和Web服务的空间信息服务及应用集成体系

Geospatial Information Service and Application Integration Architecture Based on GeoAgent and Web Services

本文在简要介绍GeoAgent和基于GeoAgent的空间信息服务的基础上,探讨了GeoAgent和Web服务相互集成的几种可能模式,提出了一个基于GeoAgent和Web服务的空间信息服务及应用集成体系,并对该体系的数据层、基于GeoAgent的空间信息服务层、基于GeoAgent的Web服务层、基于Web服务的服务流层及应用层等五个层次作了详细说明,该体系能够为数字城市中空间信息处理能力在不同层面的共享和互操作,以及空间信息服务和其他应用/服务之间的集成提供有效的机制。

Based on the introduction of GeoAgent and GeoAgent-based Geospatial Information Service,the paper gives some potential models of the integration of GeoAgent and Web Services,and proposes the architecture of Geospatial Information Service and Application Integration based on GeoAgent and Web Services. The architecture can take full advantage of GeoAgent and Web Services,overcome the disadvantages of current application model and integration model of existing Geographic Information System,and serve applications of Digital City that need Geospatial Information Service well. The major layers of the architecture are discussed also,including Data Layer,GeoAgent-based Geospatial Information Service Layer,GeoAgent-based Web Service Layer,Web Service-based Service Flow Layer,and Application Layer.
